1998 - 2006

There is a large body of evidence, based on over 20 years of randomised controlled trials
(RCTs), for a specific form of cognitive behavioural therapy (CBT), CBT for insomnia
(CBT-i), being an effective and long-lasting treatment for 50%–70% of patients.

2003 - 2006

Pharmacological therapies are widely used in primary care, but there is limited evidence
for their benefit in chronic insomnia and increasing
evidence that these medications are associated with long-term risks,
particularly in an older population.

2004 - 2012

Several small-cohort studies and two RCTs to date have evaluated
online CBT-i and shown promising results but with varying effect sizes.

CBT-i tackles factors that maintain insomnia over time,
including sleep-related dysfunctional cognitions, behaviours which
perpetuate insomnia, and dysregulation of the homeostatic sleep drive.

2014

In the most recent study into the effectiveness of sleepstation, there was a
significant increase in sleep efficiency and sleep latency after intervention;
with modest improvements in total sleep time. The majority of users reported
improved sleep quality. It was concluded that online CBT-i can be designed
to deliver personalised therapy with good reported outcomes and high
compliance rates in those who start therapy.

2016 - 2017

Several RCTs and studies show that understanding and treating disrupted
sleep through CBTi could provide a key route to improving mental health.

In the largest ever RCT of a psychological treatment for mental health,
individuals who received online CBTi showed reduction in insomnia as well
as improvements in depression, anxiety, and psychological well-being.
